SPINNING-MACHINE.

Specification of Letters Patent.

Patented Mar. 9, 1915.

Application filed September 18, 1912. Serial No. 721,031.

To all whom it may concern:

Be it known that I, PAUL WALLACE, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Spinning-Machines, of which the following is a specification.

My invention relates to textile machinery and consists of mechanism for winding yarn on to bobbins or other receptacles. My in vention can also be used for spinning, twisting or doubling of yarns.

Heretofore in machines for winding and twisting yarn, bobbins having bores extending through their entire length were placed over spindles and the rotation of the spindle caused yarn to be wound thereon; the yarn passing through eyelets or rings in carriers and in each case requiring the bobbin or other receptacle to be lifted bodily from the spindle. In order to produce the necessary drag the bobbins were made to rest upon washers or other means which could not be controlled to suit different grades of yarn and are often varied during the winding of single sets of bobbins causing unevenness of wind and twist of the bobbin and yarn. Also, in machines such as the well known cap frame and flier frame it is necessary before removing a bobbin to lift the flier or cap and then to bodily lift the bobbin therefrom.

One object of my invention is to provide a machine of the above described type in which a proportionate and constant drag can be exerted for any quality and count of yarn to be wound.

Another object is to be able to change the degree of drag quickly and accurately to suit any quality or count of yarn.

A further object is to permit of easy inserti on and removal of the bobbins. V

A still further object is to so construct the mechanism that the yarn may be easily and quickly threaded into its proper winding position and that the machine may be manufactured and maintained at a low cost and easy of operation.

These and other advantages which will be brought out in the following specification I attain in the following manner, reference being had to the accompanying drawings in which,

Figure 1, shows suificient of a yarn winding machine to illustrate my invention; Fig. 2, is a transverse sectional view on the line aa, Fig. 1; Fig. 3, is a transverse sectional view on the line bb Fig. 1; Fig. 1, is a sectional view taken on the line 0-0 Fig. 2 showing the winding wire and whirl flier in full lines; Fig. 5, is a sectional view taken on the line cZ-d Fig. 1; Fig. 6, is a detail plan View of a winding wire which I employ; Fig. 7, is a fragmental view showing a form of drag-rod that I employ; Fig. 8, is a sectional plan view through the flier and showing a modified form and arrangement of the winding wire; Fig. 9, is a modified form of drag producing means; and Fig. 10 is a fragmentary elevation of a portion of my invention shown on a reduced scale.

Referring to the drawings, 1 is the end frame having a rack 2 rigidly secured thereto, said rack forming the support for a plurality of bobbin winding mechanisms of which only one will be described in detail hereinafter. A builder plate 3 is movable up and down by a series of rods t which may be operated by any well known mechanism. These rods 1 in the present instance pass through the spindle rail or rack 2; the latter forming a guide therefor. A flanged sleeve 5 passes through the rack 2 and the flange rests on the upper face of the latter and forms a bearing for a whirl or pulley 6. A tube 7 forming a drag hearing as will be described hereinafter, is rigidly secured to the stationary sleeve 5 and passes through the whirl 6 thereby forming a journal for the latter as is clearly shown in Fig. 1. Two arms 8, in the present instance diametrically disposed extend upwardly from the whirl 6 and are connected at their upper ends by a bridge or plate 9; the latter having a depending journal pin 10 and an upwardly extending sleeve 11 rigidly secured thereto; said latter sleeve being recessed or cutaway at 12 and 12 for threading purposes as will be hereinafter more fully described. The top board 13, having a threading eyelet 14 passing therethrough, has a depending sleeve 15 which is adapted to telescope the upper end of the sleeve 11 and form a journal for the latter. A drag-rod 16, having a hooked arm 17 and head 18 rigidly secured at is upper end, passes through the tube 7 and through a drag-varying bar 19; and a compression spring 20, having one end secured to the rod 16 and the other end pressing against the lower face of the drag-varying bar, serves to hold the arm 17 in frictional contact with the upper end of the tube 7. A threaded bolt 21 is secured to the drag-varying bar 19 and loosely passes through. a bracket 22 rigidly secured to the frame 1. A threaded-hand wheel or nut 23 is operable on the threaded portion of the bolt 21 so as to lower the bar 19 to compress the spring- 20 and thereby increase the amount of friction between the arm 17 and the upper end of the tube 7.

In the present instance the yarn receptacle is in the form of a solidbobbin 24 having a recess 25- at its upper end and a recess 26 at its lowerend; the recess 25- being adapted to receive the lower end of the pin 10 and. the recess 26 being adapted to receive the head 18 of the drag rod 16, in a manner that the bobbin is free to move around the pin '10 and the head 18. The lower end of the bobbin is provided with a pin 27 which projects into the path of the hooked end of the arm 17 so as to abut the same and prevent of a complete rotation of the bobbin around the drag-rod head 18. A compression spring 28 encircles the pin 10 and, by pressing against the bridge 9 and the topof the bobbin 24, tends to keep the latter in engagement with the head 18 during the winding operation. However, there is sufficient space between the lower end of the pin 10 and the bottom of the recess 25 that the bobbin, if manually raised against the-action of the spring, will be clear of the upper end of the head 18 and may be easily removed.

The builder plate 3 hasan aperture 29 for each bobbin and of such a diameter as to allow the freerotation of the arms 8 on the whirl 6. An annular ledge 30 is formed around the aperture 29 and forms a seat'for a winding wire 31 as clearly shown in Figs. 1, 2, 3, 4, and 6; the free ends of the winding wire 31 being respectively coiled or turned around respective arms 8 so as to be free to move longitudinally thereon. A ring plate 32 issecured against the upper face of the builder plate'3by screws 33 and acts to confine the winding wire between the ledge 30 and the lower face of the ring plate 32. The flanged sleeve 5 is provided with oil recesses 34 so as to lubricate the tube 7.

The operation is as follows :The'empty bobbin is best inserted when the builder plate is in its uppermost position and by causing the lower end of the pin 10 to-register with the recess 25. The bobbin is then raised so as to compress the spring'28 as shown in Fig. 5 until the bottom of the bobbin may be slid over the head 18' of the drag rod 16, the bobbinmay then be released and the expansion of thespring 28 will cause the head 18 to project within the recess 26 and the bottom of the bobbin to rest on the arm 17 as is shown in Fig. 1. The hand wheel 23 may then be moved in order to place the required amount of downward pressure on the drag or friction-producing rod 16 according. to the quality of yarn to be spun. The whirl is then rotated by any well known mechanism, which is not shown in the drawing, and the arms 8 tend to rotate the winding wire; the yarn having been threaded through the eye 14, sleeves 15 and 11 and out of one of the cutaway portions 12 or 12*, around one arm 8, through one of the curled portions of the winding wire 31, to the bobbin. It will thus be understood that the yarn guide or wire 31 rotates at the same speed as the arms 8 and is, at the same time, raised and lowered by the builder plate to form.- the building of the-bobbin. The drag of the bobbin is produced by the pin 27 engaging, the hooked end of the arm 17 for the reason, as before stated, that the arm 17 is in frictional engagement with the top end of the stationary tube 7.

It will thusbe seen with this construction that the drag is under absolute control of the operator, that by simply turning the hand wheel 23, or other equivalent device, any degree of drag may be obtained to suit the yarn being spun. Also, it is obvious that the winding of the yarn is positive, as the mechanism which forms the direct wind is movable directly with the whirl. Also,

that there is a bearing for the winding mechanism which is supported both by the rack 2' and by the-top board- 13 so that there is absolutely no unnecessary vibration of the machine, this produces a very even lap of the yarnon thebobbin. This latter advantage is equally true of the support of the bobbin itself, as the bobbin is journaled at its base and top on journals which are rigidly secured.

In Fig. 9 is shown a modified form of mechanism for producing a drag on the rod 16. Inthiscase the drag is caused by plates 35 and 36 acting against the atmosphere, these plates are made telescopic and slide one. on theother to increase or decrease the surface area. This construction may be used in cases where there is very slight changes in-the degree of drag required such as when winding yarns of very delicate and soft texture.

In my invention the whirl 6, arms 8 and bridge 9 form a flier which is closed at both endsand which is supported at both ends; the winding wire being confined absolutely tothe path of movement of the-flier.

While I have shown the winding wire of a definite construction and having portions embracing the flier it will be understood that any means may be employed for looping the thread and holding it in a constant position relative to the rise and fall of the builder plate, for example, a winding Wire 31 may be slidably secured to an annular flange 30 on the builder plate as shown in Fig. 8 and threaded from the yarn receptacle so that a portion of the flier, such as an arm 8, will contact with the yarn and thereby cause the wire 31 to move at the same speed as the flier.

While I have only shown one hand wheel 23 and threaded bolt 21 for moving the drag-varying bar 19 it will be understood that any number of them can be used and the drag-varying bar 19 can be supported and guided in any manner.

By having a pin 27 to form the turning means for the arm 17. and rod 16, a construction is provided which allows a certain amount of motion between the drag rod 16 and the bobbin and thereby compensates for variations in the speed of the several parts in the machine. For example, if for any reason, such as a variation in the quality of yarn being wound or a sudden change from a high to low speed of the machine, the bobbins should tend to hold back, they could do so Without being compelled to turn the friction rod 16 and possibly straining the yarn.
